About

A conditioning polymer derived from animal collagen that provides anti-static and moisturizing benefits to skin and hair formulations.

Steardimonium Hydroxypropyl Hydrolyzed Collagen is a quaternary ammonium derivative of hydrolyzed collagen (typically bovine or porcine source) used as a conditioning agent in cosmetics. It is not subject to EU restrictions under Regulation 1223/2009. The ingredient provides substantivity to skin and hair, reducing static charge and improving tactile properties. Formulators should note the animal source for vegetarian/vegan labeling requirements.
